You should definitely head over there, sign up, and ask for their help on these issues.<br /><br />https://groups.yahoo.com/neo/groups/polysix/info<br /><br />ChipChiphttps://www.blogger.com/profile/10352943033779293161noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-91460320844730735452016-04-06T15:45:15.923-04:002016-04-06T15:45:15.923-04:00Great project..Hay I have an issue with a Polysix ...Great project..Hay I have an issue with a Polysix and I wonder if you could point me in the right direction. <br /><br />I have a Korg Polysix which I do not know too much about but have a couple issues:<br /><br />First, I can get somewhat normal sounds, use programmer, change banks/presets, write to presets, use bend and mg wheels, use key assign mode, etc. I can get some cool fat synth and string sounds typical of this synth but something is not right.<br /><br />1) When I turn the CUTOFF dial, I get sort of a muffled warbly sound till 11 O&#39;Clock then it clears up between 11 and 5 O&#39;Clock (I suspect something is wrong with the Contour pot -or- something else in the signal chain...I have used Deoxit extensively on the pot and still have the issue). A gentleman who was looking to buy it said he thought it might be more than a deoxit fix as it seem more like a muffled warbly sound rather than a typical scratchy pot. <br /><br />2) The attack pot, resonance pot and (maybe the speed intensity pot) seem to have some of the same symptoms but not as obvious as the cutoff pot. Hard to tell as I don&#39;t as so many things on a synth are interdependent and not sure what affects what exactly and how they should behave exactly.<br /><br />Any ideas?<br /><br />Like I said, I can use the presets and get a decent synth sound and most functions seem to work fine except the wave shaping (whatever you call it)...<br /><br />Note: There was a battery mod performed on the board, there was slight surface etching but apparently traces checked out (I assume as I am getting sounds and 80% normal function). Also all key contacts have been replaced.<br /><br />Could this be as simple as bad pots -or- is there an IC (one that affects countour resistor, cap (or maybe the board the pots all sit on) that I might need to look at?<br /><br />Love the synth and would love to get it to 100% but just a couple nagging issues. <br />Thanks for any direction and help you can provide.GoodGuyhttps://www.blogger.com/profile/10864196340994145785noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-18046662456484405462015-11-08T12:34:15.298-05:002015-11-08T12:34:15.298-05:00The Kiwi mod is sweet, but to make the synth veloc...The Kiwi mod is sweet, but to make the synth velocity sensitive, you need more modifications than Kiwi does. It&#39;s these extra modifications to the circuitry that had to be figured out. <br /><br />What I showed here is one approach to adding velocity sensitivity. Maybe the Kiwi mod folks will incorporate this (or some other approach) in the future. That&#39;d be great. I had fun just showing that it *could* be done. <br /><br />Hopefully someone else can package it into a form that would make it easy for others to do.<br /><br />Thanks for reading!<br /><br />ChipChiphttps://www.blogger.com/profile/10352943033779293161noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-50388762227476742952015-11-08T12:11:32.744-05:002015-11-08T12:11:32.744-05:00Almost surprised that the Kiwi mod doesn&#39;t eve...Almost surprised that the Kiwi mod doesn&#39;t even allow velocity via MIDI? I certainly would do this keyboard mod, but realize it&#39;s more DIY than something that could be bought?<br />Key Manhttps://www.blogger.com/profile/09019499460028607916noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-43586457105956200722015-11-08T10:52:51.726-05:002015-11-08T10:52:51.726-05:00Nice work !Nice work !Tony McAdamhttps://www.blogger.com/profile/14298287318534550303noreply@blogger.com
